Viability analysis of vector control

In [40] the effect of introducing control through mosquito repellents used in textiles,

paints and other household items (curtains, furniture) in a model for a vector-borne dis-

ease of a susceptible-infected-removed type for the host and susceptible-infected for the

mosquito vector is investigated. Modeling of control measures in the context of vector-

borne diseases has focused on optimal resource allocation [14, 37, 38, 47, 46, 54]. Stability

analysis of epidemiological models investigates the asymptotic convergence of solutions to

equilibria with specific properties, but does not answer the question of transient dynamic

behavior.
